GUIDE MEANS FOR BRICK-CUTTING MACHINES.

To all whom it may concern Be it known that'I, ANDREW H. NELSON, acitizen of the United States, residing at Mason City, in the county of:Cerro Gordo and State-of Iowa, have invented certain new and usefulImprovements in Guide Means for Brick-Cutting Machines, of which thefollowing is a specification.

Myinvention relates to improvements in machines for cuttingastrip ofplastic material, into bricksor'the like, and has particular referencetoguide means for the arms which carry the plastic materialcuttingelements orwires.

1 An important object of the invention is to provide means of the abovementioned character, adapted to coeperate with the arms of the reel,carrying the cutting elements or wires, so. that such cuttingelementswill descend perpendicularly, through the'plastic material, for properlycutting the same.

. A further object of the invention is to provide guide means of theabove mentioned character, adapted .to properly take .up shocks, uponits contact with the rollers carried by the arms ofthe reel..

- part of A further object of the invention is to'provide means of theabove mentioned character, which are simple in construction, inexpensiveto manufacture, and convenient in use.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanyingjdrawings forming a this specification and in whichlike numerals are employed to designate, like parts throughout the same,Figure-l is aside elevation of a'portion of a brick'cutting machine,showing my guide means applied- 2 isan enlarged fragmentary sideelevation of one guide, embodied in the invention, parts being shown insection, Fig. 3 is a frontelevationof the guides, taken at a rightangletothe-showing in Fig. 1, with arts broken away and portions of themachine omitted,-Fig. 4 is a detail-elevation of a socketelen1ent,fland, Fig. 5 is a fragmentary side elevation of a travelingsupport or conveyer. Y

It is old in the art to provide a brick cutting machine embodyinggenerally a traveling endless'conveyer or support, for holding the baror slab of plastic'material. This endless conveyer is provided withoutwardly Specification of Letters Patent. Patented Dec 21, 1915.Application filed September 7, 1915. Serial No. 49,266. i I

arms of a reel, to turn it. These arms carry wires or other cuttingelements which descend through the plastic material upon the travelingsupport, and cut the same into bricks or the like. Such a constructionis illustrated in the patent granted to J. Ben'- sing, No. 411,638,underdate of September 24, 1889. In view of the fact thatthis generalconstruction is well known, the entire machine will not be described in'this applis cation, but only sufliciently to illustrate the applicationof my improvement, to a machine of this general type. j The numeral 10designates a traveling support or endless conveyer, embodying sectionsor links 11, pivotally connected by means of apertured knuckles 12,receiving pins 13, also carrying rollers 14. These rollers travel uponsuitable tracks 15, for guiding the traveling support during itsmovement. Any suitable means may be employed to effect the travel of thesupport or endless conveyer. Rigidly connected with each side of eachsection or link 11 is an outwardly ex tending standard 15, which isvertical when contacting a portion of a reel, to be described.

, The numeral 16 designates vertical-stationary standards, having theirupper ends apertured for' receiving a horizontal transverse shaft 17,upon which are rigidly mounted wheels 18. Pivotally connected with theWheels 18, as shown at 19, are pairs of transversely alined radiallydisposed arms..20, adapted to partake of swinging movement within thespacebetween lugs 21. Each arm 20 is held in the normal radiallydisposed position by a spring 22 or the like, asshown.

As more clearly shown in Fig. 3, the arms 20 are provided at their outerends with apertures, receiving shafts 23, clamped therein by, bolts 24or the like. These bolts are provided at their inner ends with suitablemeans for connection with a cutting wire or element 25, as shown.Rotatably mounted upon the shafts 23 are inner and outer rollers 26 and27, for a purpose to be described.

The numeral28 designates preferably angularly arranged support-bars,'the' lower ends of which are preferably provided with slots 29,receiving clampingbolts. 30, carried by the verticallystationaryst'andards 16. Pivotally connected with the outer portions ofthe support-bars 28 by means, of

elongated" slots 33, receiving clampingbolts 34c, rigidly attached tothe stationary verti} cal standards-1-6 asshown It is thus ap parentthat the support bars 28 are rigidly held in place upon the'verti'cal'standards"16" and may be angularly adjusted, when desired."

The numeral 35 designateslongitudinally curved guides, which arepreferably rigid and are: arranged upon opposite sides. of: thetraveling supportv 1O/and1 outwardly of; the same; The: upper :end ofveach guide 35is bent to formza preferably stnaight substan tiallyjlhorizontal portion; 36}, mountedz to slide or reciproeateiwithintubular-socket 3 7', as moreinclearly showninv Fig. 2.

As more clearly shown in Figs. 1 and12;

v The operation cram machine is as follows: The traveling support 10moves in [the 'dii'ection'of the'arrow, and the standards 15 contactwiththe rollers 27 carried by'"each pair of arms 20, as illustrated in Rigl. The? reel. embodying the arms 20 is thus rotated by the movement ofthe standards '15.
